REINFORCED HANDLE.

Application filed July 22, 1907.

To all whom it may concern.

Be it known that I, EDWIN C. I-loLToN, a citizen, of the United States, residing at Somcrville, county of Middlesex, and State of Massachusetts, have invented certain new and useful Improvements in Reinforced Handles.

My invention relates to a unitized handle or handle-wheel for valves, brakes, presses, steering gears, doors, door-stops, etc. Ham dles for these articles are now usually made either entirely of metal and in one piece, or of two or more substances ard in two or more parts, one of a non-metallic nature and the others of various metals, and held together by nuts, screws, etc, in a manner that seldom proves satisfactory, rigid or durable,-the non-m tallic part annoying the users by its tendency to warp and. its frequent liability to split. I produce this unitization by con structing a nonanetallie handle internally cored to form a mold, the parts of which are in such re .ions one to another that when all its interstices are lowed with molten metal a cast spider handle or hand-wheel is produced, the parts of which, as they restwhen cooled within this mold, are so opposingly yet strongly interwoven, intermingled and bound that it becomes a rigid. unbrealnihle casting unit handle of great strength and durability; possessing advantages in points of economy in cost of manufacture. simplicity of (:(mstruction, and beauty of design; a handle that will not split, nor twist, nor pull apart, nor be crushed by any reasonable tangential stress, thrust or pressure; not become loosened. by long or (XCQxSlVQ service: nor the two substances become loosened. by the swelling or .irinkim; of the r fivering', also a non-con ductor of electricity, or heat, if so desired, as in a handle or handle-wheel for steam val es. etc. (the small ratio of metal to the non-metallic part, reducing to a minimum the degree of heat atthe ouf vr circumference of the web or rim) In the accompanying; drawings, Figure 1 illustrates the top side of the article in which my invention is embodied. Fig. 2, a reverse view of the. same partly broken away, showing the metal spider tasting resting in its mold. Fig. i. illustrates a section of the handle. Fig. 4 represents the spider, or metal skeleton of the hand-wheel, as it appears stripped of its mold or covering. Fig. 5 is Specification of Letters Patent.

Similar letters refer to s milar parts throughout the several drawings. 7

A is a general view of the hand grip part and a mold for producing a unitized handle or handle-"wheel for valves, etc.; this part is of hard metal, or of a non-metallic sub stance such as papier mtiche, cement, clay, glass. rubber, gutta percha, wood pulp, wood, etc., but preferably of these noninetallic substances some of which are frangible, and hence is referred to hereafter as of a nonmetallic substance only, and as of wood only. This non-metallic part in its primary, initial and independent state, is in fact a mold, and in its outer form, B, of a shape most convenient for the purposes intended (sec contour as in Fig. 3); it is made with a thick or heavy rim, A and with a rounded or bead-like center web, JAE with the center of the top side concave as at A this form gives a larger sur face for the hand than the old forms, and hence a cooler one, and the concave depression allows of the placing of the nut or screw head at a point so low as to prevent the head of the nut or screw burning the palm of the hand when operating it. in the center of the other or inner side, (3,.Fig. is a hole H. common in all forms of those molds or handles. It is either round, square or many sided. but preferably round; it may be of various depths and diameters, and have various curves and angles (according to the measurements demanded by the various sizes. styles and articles it may be applied to). thereby forming the steps, E, and E, as shown in Fig. 3; with the side or rise of that portion that is the second widest in diameter at right angles to the bottom line of the first or widest tread or step as at F or the side of the recess in the 'inner side of the handle 'may be beveled inwardly as at F in Fig. 6.

in the bottom of the step E (Fig. 3) and the bottom of the recess Fig. til are two or more round holes? S. and S respec tivcly, that extend partly through the web of the mold; there are also two or more round or square holes (preferably round) extending laterally and at an angle from the side of the hole or recess in the handle and the 1nterspace nearly through the mold or handle; these I term the lateral holes, I. A groove, G, shown in Fig. 3, is made around the entire side or circumference of that portion of the mold or matrix that I term the second step, extending laterally from the side or rise of this second step into the web of the mold or handle; this groove may be placed so as to bisect in its course, so far as it may extend, the two or more lateral holes mentioned above, (this position of the groove produces the flange of the spider in that position that ties and strengthens and binds its spokes together); or this groove may pass around and into the Web of the handle or mold at or near the top or bottom of the recess and into the web to various depths and at various angles as at G Fig. 6. The smaller portion of this common central hole, H, extends through theweb of the handle or hand wheel for valves, etc., in which the hard metal stopper, plug or hub J Fig. 5, with its notches N, and its chamfered side, L, fits, resting on its seat, M, thereby stopping the flow of the molten metal Q its face K forming a seat for a nut, screw or cap. This form of construction prevents it from turning or moving in the softer metal when strain, stress or force is exerted upon the handle). The wood or non-metallic substance I designate as D.

The unitization of a valve Wheel. etc.. is obtained by inserting the small end of the stopper, plug or hub in the central hole in the web. the larger part, or seat, resting on the second step. When thus placed the molten metal is flowed between the side of the wood and the chamfered end and notched side of the stopper, plug or hub filling the small lateral holes and groove aforesaidand and interstices. thereby forming the cast of the spider the latter being seen in Fig. 4., stripped of its molddeunitized-with its spokes R radiating from the hub into the web and rim of the handle. adding great strength to the wheel and preventing the hub or shank turning in the wood. and binding the parts firmlv together. Those spokes are strengthened and tied by the flange 0. both transversely attached to the hub or shank J, and the hole P in this plug hub or shank is adapted to receive a spindle. stem or rod: and that portion of the handle other thanthe wooden or non-metallic portion is in itself a strong and durable metal handle or handle-wheel; and hence in this improvement l produce a metal handle or handle-wheel rigidly incased within and unitized with a non-metallic handle or hand-Wheel in such a manner that each adds greatlv to the natural or individual strength of the othera much needed and desirable result being then achieved.

In Fig. 6 the drawing shows the above principles as applied to a handle or knob for doors, etc. In this form the central hole does not extend through the web, but the lateral holes and grooves are seen in the same relative positions as in Fig. 3. In this form the stopper, plug or hub, with extended shank is applied-to the inner side of the mold or handle only, extending nearly to the bottom of the hole H, with its Wider or outer part fitting, filling and resting in the first or widest step. In this form of a mold or handle the process of unitization is accomplished by placing the stopper, plug or hub J in its seat in and over the hole H and then pouring the molten metal into the hole P thereby filling the lateral holes, groove, interspace and-interstices, as for a hand-wheel for valves. The outer forms in handles of this class may vary, some being round or circular, others oval, oblong, elliptic or with many sides.

It will readily be seen that the features peculiar to the construction of this common central hole as embodied in my invention, are capable of numerous modifications of the angles, diameters, curves, etc, and 'of being applied to various articles, and that the general results are virtually the same, regardless of the outer and inner contours and measurements.

Having described my invention and set forth its merits, what I claim is l. A reinforced handle consisting of a body provided with a central aperture and passages extending into close approach to the outer periphery thereof, and a reinforcing metal insert filling said central aperture and passages and serving to bind the parts of the body together.
